Pete Seeger, folk singer and activist whose music and straight talk inspired generations of musicians and activists, has died. He was 94. Known for songs like “If I Had a Hammer,” “Turn, Turn, Turn,” and “Where Have All the Flowers Gone”, Seeger–who joined the Young Communist League (YCL) in 1936 and the Communist Party USA in 1942, eventually drifting away from them in the early 1950s–performed for troops in the South Pacific during World War II. He was convicted of contempt of Congress after refusing to answer questions at the House Un-American Activities Committee.
